Answer:

The second one:
8x^(2)y+7x^(2)-5y^(2)+3x-2+2x^(2)y-x^(2)-2y^(2)-3x-4

Explanation:

You have to combine the like terms (any numbers with the same variables and exponents)


8x^(2)y+2x^(2)y=10x^(2)y, 7x^(2)-x^(2)=6x^(2), -5y^(2)-2y^(2)=-7y^(2), 3x-3x=0, -2-4=-6

If you put all of the answers together you get
10x^(2)y+6x^(2)-7y^(2)-6
